Introducing the Network Interface Cards
Rockwell Automation 1784-PKTx family PCI cards connect PCs to PLC controllers on Data
Highway Plus (DH+) or SLC processors on DH-485 networks for easy programming and
data acquisition. I/O scanner functionality is also available in the cards so they can be used
with soft-control or embedded-control engines. And, because these cards incorporate the
Universal PCI Card Standard, they are compatible with almost any PC. If general
programming, configuration, and monitoring capabilities via an industrial or desktop PC are
required, these cards are a necessity.
Your 1784-PKTx network interface card (cat. nos. 1784-PKTX and 1784-PKTXD) is a PCI
(Peripheral Component Interconnect) universal card that must be inserted into a PCI bus
slot. A universal card can be placed into a PCI bus slot that is keyed for either 3.3 Volt or 5
Volt signalling. This card may also be placed in a 64-bit slot, although it will not use the
extended 64-bit operation. Table 1.1 outlines features supported by the PKTx cards.
